Thanks for your help. It was an empty mime type somehow added to the server. After removing, it worked fine.

I am able to install all plugins except 'Nop Product Ribbons' and 'Nop Brooklyn Theme' (the plugin). I tried restarting NopCommerce, cleaning cache, etc.

The error I am getting is "Value cannot be null. Parameter name: key"

Stack trace:
